What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world.
That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and
voted up or down.

Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted
to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning,
there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

I used to use the CIDR for it, but I wanted a really quick list, and over both the 192.168.0.* and 192.168.1.* ranges. I could use CIDR /16, but that takes considerably more time, and scans a lot of uncommon network configurations. I used to grep for my IP, but it's really uneccessary.

@mpb:

That is neat! I've been looking for a way to get around that limitation. Sadly, the arp lookup is really slow, and only returns two of 8 hosts currently running on my network.

@ atopnce:

Yeah, I realized that immediately afterward :-/. I will do better next time. However, I did use more newbie friendly search terms, with the net effect, rather than the literal description of the process, so I decided to keep it up.
